G'Day Matt & Paddlewise,

Your explanations confirmed and developed my understanding of previous
posts. A couple of minor questions.

What is the difference between "weatherhelm" and "weathercock"? Does one
describe wind effects and the other wave effects on a kayak?

Secondly you mentioned the effect of gravity on energy consumption. Is this
solely due to the increased cadence and therefore the increased frequency of
lifts for a paddle and associated water near the end of a stroke? This
assumes there is no significant energy use against gravity in 'climbing'
waves unless one is pushing hard into surf.

All the best, PeterO
